Enhancing the robustness of uplink transmission

ABSTRACT

Techniques for controlling parameters for uplink transmission associated with a device to facilitate improving a communication condition metric(s) (CCM(s)) of the uplink transmission are presented. A communication management component (CMC) can determine whether CCM satisfies a first threshold CCM. If CCM does not, CMC can modify a parameter(s) to reduce a number of resource blocks or an MCS value to improve the CCM. If respective minimum threshold levels have been reached for the number of resource blocks and MCS value, and CCM still is not satisfying the first threshold CCM, CMC can modify a parameter to increase an amount of repetition of data packets for uplink transmission (unless a maximum threshold amount of repetition is reached). If CCM satisfies an applicable threshold CCM for a defined amount of time, CMC can modify parameters to increase the number of resource blocks, increase MCS value, or reduce repetition of data packets.

DETAILED DESCRIPTION

One or more embodiments are now described more fully hereinafter withreference to the accompanying drawings in which example embodiments areshown. In the following description, for purposes of explanation,numerous specific details are set forth in order to provide a thoroughunderstanding of the various embodiments. However, the variousembodiments can be practiced without these specific details (and withoutapplying to any particular network environment or standard).

Discussed herein are various aspects that relate to controlling a groupof parameters (e.g., resource block parameter, modulation and codingscheme (MCS) parameter, packet repetition parameter, and/or anotherdesired parameter) for an uplink transmission associated with acommunication device (e.g., wireless communication device) to facilitateenhancing (e.g., improving) the robustness of the uplink transmission.The disclosed subject matter can significantly improve communication ofinformation between wireless communication devices and a communicationnetwork (e.g., wireless communication network) and network efficiencyassociated with the communication network.

The various aspects described herein can relate to new radio, which canbe deployed as a standalone radio access technology or as anon-standalone radio access technology assisted by another radio accesstechnology, such as Long Term Evolution (LTE), for example. It should benoted that although various aspects and embodiments have been describedherein in the context of 5G, Universal Mobile Telecommunications System(UMTS), and/or Long Term Evolution (LTE), or other next generationnetworks, the disclosed aspects are not limited to 5G, a UMTSimplementation, and/or an LTE implementation as the techniques can alsobe applied in 2G, 3G, 4G, or LTE systems. For example, aspects orfeatures of the disclosed embodiments can be exploited in substantiallyany wireless communication technology. Such wireless communicationtechnologies can include UMTS, Code Division Multiple Access (CDMA),WI-FI, Worldwide Interoperability for Microwave Access (WIMAX), GeneralPacket Radio Service (GPRS), Enhanced GPRS, Third Generation PartnershipProject (3GPP), LTE, Third Generation Partnership Project 2 (3GPP2)Ultra Mobile Broadband (UMB), High Speed Packet Access (HSPA), EvolvedHigh Speed Packet Access (HSPA+), High-Speed Downlink Packet Access(HSDPA), High-Speed Uplink Packet Access (HSUPA), ZIGBEE, or anotherIEEE 802.XX technology. Additionally, substantially all aspectsdisclosed herein can be exploited in legacy telecommunicationtechnologies. Further, the various aspects can be utilized with anyRadio Access Technology (RAT) or multi-RAT system where the mobiledevice operates using multiple carriers (e.g., LTE Frequency DivisionDuplexing (FDD)/Time-Division Duplexing (TDD), Wideband Code DivisionMultiplexing Access (WCMDA)/HSPA, Global System for MobileCommunications (GSM)/GSM EDGE Radio Access Network (GERAN), WI-FI,Wireless Local Area Network (WLAN), WIMAX, CDMA2000, and so on).

As used herein, “5G” can also be referred to as New Radio (NR) access.Accordingly, systems, methods, and/or machine-readable storage media forreducing interference on reference signals from other co-channelreference signals, and improving the channel estimation performance forCSI estimation and data detection, in 5G systems, and other nextgeneration systems, can be desired. As used herein, one or more aspectsof a 5G network can comprise, but is not limited to, data rates ofseveral tens of megabits per second (Mbps) supported for tens ofthousands of users; at least one gigabit per second (Gbps) that can beoffered simultaneously to tens of users (e.g., tens of workers on thesame office floor); several hundreds of thousands of simultaneousconnections supported for massive sensor deployments; spectralefficiency that can be significantly enhanced compared to 4G;improvement in coverage relative to 4G; signaling efficiency that can beenhanced compared to 4G; and/or latency that can be significantlyreduced compared to LTE.

Multiple Input, Multiple Output (MIMO) technology can be employed incommunication networks, wherein MIMO technology can be an advancedantenna technique utilized to improve spectral efficiency and, thereby,boost overall system capacity. Spectral efficiency (also referred to asspectrum efficiency or bandwidth efficiency) refers to an informationrate that can be transmitted over a given bandwidth in a communicationsystem.

For MIMO, a notation (M×N) can be utilized to represent the MIMOconfiguration in terms of a number of transmit antennas (M) and a numberof receive antennas (N) on one end of the transmission system. Examplesof MIMO configurations used for various technologies can include: (2×1),(1×2), (2×2), (4×2), (8×2) and (2×4), (4×4), (8×4). The configurationsrepresented by (2×1) and (1×2) can be special cases of MIMO known astransmit and receive diversity.

In some cases, MIMO systems can significantly increase the data carryingcapacity of wireless communications systems. Further, MIMO can be usedfor achieving diversity gain, which refers to an increase insignal-to-interference ratio due to a diversity scheme and, thus, canrepresent how much the transmission power can be reduced when thediversity scheme is introduced, without a corresponding performanceloss. MIMO also can be used to achieve spatial multiplexing gain, whichcan be realized when a communications system is transmitting differentstreams of data from the same radio resource in separate spatialdimensions (e.g., data is sent/received over multiple channels, linkedto different pilot frequencies, over multiple antennas). Spatialmultiplexing gain can result in capacity gain without the need foradditional power or bandwidth. In addition, MIMO can be utilized torealize beamforming gain. Due to the benefits achieved, MIMO can be anintegral part of the third generation wireless system and the fourthgeneration wireless system. In addition, 5G systems also will employmassive MIMO systems (e.g., hundreds of antennas at the transmitter sideand receiver side). Typically, with a (N_(t), N_(r)), where N_(t)denotes the number of transmit antennas and N_(r) denotes the number ofreceive antennas, the peak data rate can be a multiple with a factor ofN_(t) over single antenna systems in a rich scattering environment.

Communication devices can communicate information (e.g., voice and/ordata traffic) to other communication devices via a communicationnetwork, which can comprise a core network that can operate to enablewireless communication between communication devices. For example, awireless phone (e.g., mobile, cell, or smart phone; or electronic tabletor pad) can connect to and communicate with a wireless communicationnetwork (e.g., core network) to communicate with another communicationdevice connected to the wireless communication network or to anothercommunication network (e.g., Internet Protocol (IP)-based network, suchas the Internet) associated with (e.g., communicatively connected to)the wireless communication network.

In wireless communications, it can be desirable (e.g., important) forthe uplink transmission from the communication device to the basestation to be sufficiently robust, for example, to maintain a desirablewireless radio link between the communication device and base stationand to mitigate and/or avoid failure of the radio link. For example,with regard to 5G NR, the uplink transmission at least will carry (e.g.,communicate) the negative acknowledgement message or acknowledgementmessage (NACK/ACK) for traffic (e.g., voice or data traffic)communicated via the downlink transmission (e.g., NR DL). The uplinktransmission also can carry data traffic, for example, when EN-DC(Evolved-Universal Terrestrial Radio Access-New Radio (EUTRA-NR) dualconnectivity) technology is employed, wherein EN-DC can enable and allowthe communication device to exchange data between the communicationdevice and an NR base station while the communication device also issimultaneously connected with an LTE base station. Sufficient robustnessof the uplink (e.g., NR UL) can be desirable in order to achievedesirable (e.g., suitable, acceptable, or optimal) network performance(e.g., NR performance). Sufficient robustness of the uplink can beparticularly desirable (e.g., important) for 5G NR mmWave (e.g., timedivision duplex (TDD) mmWave 5G NR). Generally, it is expected that the5G NR uplink can be the bottleneck (e.g., the weaker link), inparticular for mmWave. There also can be issues (e.g., problems) withthe uplink with regard to other types of 5G NR technologies, such as,for example, sub-6 5G NR (e.g., frequency division duplex (FDD) sub-6 5GNR), in addition to mmWave.

From experimental field testing, it has been observed that 5G NR uplink(e.g., physical uplink control channel (PUCCH)) can be a bottleneck(e.g., a relatively weaker link) that can undesirably limit the NRperformance. For example, at the edge of NR coverage (e.g., based on aDL NR reference signal received power (RSRP) −90 dBm threshold), radiolink failure of the uplink has been observed due to a weak uplink.Another observation is that poor uplink NACK/ACK reception (e.g., lossof ACK sent by UE to the base station) can lead to an implicit NACK(e.g., base station assumes downlink transmission was not receivedbecause an ACK regarding the downlink transmission was not received bythe base station), unnecessary downlink packet retransmission, andreduction of downlink throughput, capacity, and reliability.

The disclosed subject matter can overcome these and other problemsassociated with wireless communications. To that end, the disclosedsubject matter presents techniques, methods, and systems that cancontrol a group of parameters (e.g., communication parameters, such asuplink and/or resource parameters) for an uplink transmission associatedwith a device to facilitate improving communication condition metrics(e.g., communication quality metrics), including asignal-to-interference-plus-noise ratio (SINR) and/or the implicit NACKrate, of the uplink transmission. The disclosed subject matter cancomprise a communication management component (CMC) that can determinewhether one or more communication condition metrics (e.g., SINR,implicit NACK rate, and/or another type of communication conditionmetric) satisfies one or more respective first threshold values relatingto the one or more communication condition metrics (e.g., a firstthreshold SINR, and/or a first threshold implicit NACK rate), based atleast in part on the results of analyzing communication-relatedconditions, including the SINR and implicit NACK rate, of the uplinkcommunication connection between the device (e.g., communication device)and the communication network.

If the CMC determines that a communication condition metric(s) does notsatisfy the first threshold value(s) relating to such communicationcondition metric(s), the CMC can modify one or more parameters of thegroup of parameters to improve, or at least attempt to improve, thecommunication condition metric(s) (e.g., SINR and/or implicit NACKrate), and enhance the robustness, of the uplink transmission. The groupof parameters can comprise, for example, a resource block parameterrelating to the number of resource blocks (e.g., physical resourceblocks (PRBs) utilized for the uplink transmission, a modulation andcoding scheme (MCS) parameter relating to an MCS value utilized for theuplink transmission, a packet repetition parameter relating to an amountof repetition of data packets for the uplink transmission, and/oranother desired parameter relating to communication conditionsassociated with the uplink transmission. For example, in response todetermining that a communication condition metric, such as the SINR orimplicit NACK rate, does not satisfy the first threshold value relatingto such communication condition metric, to improve, or at least attemptto improve, the communication condition metric (e.g., the SINR orimplicit NACK rate), the CMC can modify one or more parameters of thegroup of parameters to reduce the number of resource blocks utilized forthe uplink transmission by a desired amount of resource blocks and/orreduce the MCS value for the uplink transmission by a desired amount,unless the CMC determines that the respective minimum threshold levelshave been satisfied (e.g., reached) with respect to the number ofresource blocks and MCS value, in accordance with defined communicationmanagement criteria.

In some embodiments, the CMC can determine that the resource blockparameter and the MCS value parameter are to be modified at the sametime in a given step to reduce the number of resource blocks and reducethe MCS value. Alternatively, as desired, the CMC can determine thatthose parameters (e.g., resource block parameter and MCS parameter) areto be modified separately (e.g., in separate steps), wherein the CMC canreduce one of those parameters (e.g., resource block parameter) in afirst step to reduce the number of resource blocks and can reduce theother parameter (e.g., MCS value) in a second step to reduce the MCSvalue. Alternatively, the CMC can determine that first parameter (e.g.,resource block parameter) of those parameters is to be modified (e.g.,reduced), without modifying (e.g., reducing) a second parameter (e.g.,MCS parameter) of those parameters, until the first parameter has beenmodified to the point of satisfying the applicable threshold valueassociated with the first parameter, and thereafter, as desired (e.g.,as needed to achieve the desired SINR and/or implicit NACK rate of theuplink transmission), the CMC can modify the second parameter to attemptto improve (e.g., further improve) the communication condition metric.

If the CMC determines that the respective minimum threshold levels havebeen satisfied for the number of resource blocks and MCS value, anddetermines that the communication condition metric (e.g., the SINR orimplicit NACK rate) for the uplink transmission still is not satisfyingthe first threshold value, the CMC can modify the packet repetitionparameter to increase an amount of repetition of data packets for theuplink transmission by a desired amount, unless a defined maximumthreshold amount of repetition of data packets has been reached, inaccordance with the defined communication management criteria.

After modifying the one or more parameters of the group of parameters,the CMC can determine the communication condition metrics (e.g., currentSINR, current implicit NACK rate, and/or another current communicationcondition metric) for the uplink transmission, with the modifiedparameter values in place, based at least in part on the results ofanalyzing of information relating to the communication-relatedconditions, including SINR, implicit NACK rate, etc., of the uplinkcommunication connection. The CMC can determine whether one or more ofthe respective communication condition metrics (e.g., the SINR and/orimplicit NACK rate) satisfy one or more of the respective firstthreshold values relating to the respective communication conditionmetrics. If the CMC determines that the one or more respectivecommunication condition metrics do satisfy the one or more respectivefirst threshold values relating to the one or more respectivecommunication condition metrics, the CMC can determine that the group ofparameters does not have to be modified. With regard to one or more thecommunication condition metrics, for each communication condition metric(e.g., SINR or implicit NACK rate) under consideration, if the CMCdetermines that the communication condition metric still does notsatisfy the first threshold value relating to such communicationcondition metric, the CMC can determine whether further modifications ofone or more parameters of the group of parameters are to be performed toattempt to improve communication condition metric (e.g., the SINR orimplicit NACK rate) of the uplink transmission, and, if so, canimplement such modifications of the one or more parameters, inaccordance with the defined communication management criteria, includingthe respective threshold values associated with the respectiveparameters of the group of parameters.

The CMC also can modify the parameters, for example, to increase thenumber of resource blocks, increase the MCS value, and/or decrease theamount of repetition of data packets for the uplink transmission, if theCMC determines that a communication condition metric(s) (e.g., the SINRor implicit NACK rate) of the uplink transmission is sufficiently goodfor a desired amount of time. For instance, if the CMC determines that acommunication condition metric(s) (e.g., the SINR or implicit NACK rate)satisfies an applicable threshold value(s) relating to suchcommunication condition metric(s) for a defined amount of time, the CMCcan modify one or more of the parameters to increase the number ofresource blocks, increase MCS value, and/or reduce the amount ofrepetition of data packets, in accordance with the defined communicationmanagement criteria. In accordance with various embodiments, with regardto a particular communication condition metric, the applicable thresholdvalue can be the first threshold value relating to that particularcommunication condition metric or a second (e.g., different) thresholdvalue relating to that particular communication condition metric, inaccordance with the defined communication management criteria.

With further regard to the repetition of data packets, in someembodiments, the CMC can associate, add, or apply a tag to data packets(e.g., repetitive data packets) of a message (e.g., an ACK message or aNACK message) carried in the uplink transmission, wherein the tag canindicate to which downlink transmission the message repetition (e.g.,packet repetition of an ACK or NACK message) applies or is related. Forinstance, for ACK and NACK messages on PUCCH, there sometimes can be atime limitation, such as an n+x time slot, for the communication of suchmessages, wherein n and x can be respective number values. For therepetition of the data packets of the message to be recognized by thereceiver (e.g., base station, or communication network) of the message,the CMC can associate, add, or apply the tag to the data packets (e.g.,repetitive data packets) of the message to indicate the downlinktransmission (e.g., the data in the downlink message) to which theuplink message repetition (e.g., ACK or NACK message repetition) appliesor relates.

These and other aspects and embodiments of the disclosed subject matterwill now be described with respect to the drawings.

In wireless communications, it can be desirable (e.g., important) forthe uplink transmission from the communication device to the basestation to be sufficiently robust, for example, to maintain a desirablewireless radio link between the communication device and base stationand to mitigate and/or avoid failure of the radio link. For example,with regard to 5G NR, the uplink transmission at least will carry (e.g.,communicate) the ACK and NACK messages relating to traffic (e.g., voiceor data traffic) communicated via the downlink transmission (e.g., NRDL). The uplink transmission also can carry data traffic, for example,when EN-DC technology is employed, wherein EN-DC can enable and allowthe communication device to exchange data between the communicationdevice and an NR base station while the communication device also issimultaneously connected with an LTE base station. Sufficient robustnessof the uplink (e.g., NR UL) can be desirable in order to achievedesirable (e.g., suitable, acceptable, or optimal) network performance(e.g., NR performance). Sufficient robustness of the uplink can beparticularly desirable (e.g., important) for 5G NR mmWave (e.g., TDDmmWave 5G NR). Generally, it is expected that the 5G NR uplink can bethe bottleneck (e.g., the weaker link), in particular for mmWave. Therealso can be issues (e.g., problems) with the uplink with regard to othertypes of 5G NR technologies, such as, for example, sub-6 5G NR (e.g.,FDD sub-6 5G NR), in addition to mmWave.

In accordance with various embodiments, the disclosed subject matter cancomprise a communication management component (CMC) 110 that control(e.g., manage, adjust, modify, and/or tune) various parameters of agroup of parameters (e.g., communication parameters, such as uplinkand/or resource parameters) associated with uplink transmissions ofcommunication devices, such as communication device 104, to facilitateimproving (e.g., increasing) one or more communication condition metrics(e.g., communication quality metrics or values), including, for example,the SINR and implicit NACK rate, and improving (e.g., increasing) therobustness, of the uplink transmission to mitigate (e.g., reduce theoccurrence or risk of) radio link failure of the uplink transmission.The CMC 110 can control the group of parameters, for example, withregard to the physical uplink control channel (PUCCH) and/or thephysical uplink shared channel (PUSCH) associated with the uplinktransmissions of communication devices (e.g., communication device 104).The group of parameters can comprise, for example, a resource blockparameter relating to a number of resource blocks (e.g., physicalresource blocks (PRBs)) utilized during an uplink transmission, an MCSparameter relating to an MCS value (e.g., MCS index value) utilizedduring the uplink transmission, a packet repetition parameter relatingto the amount of repetition of transmission of a particular data packet(e.g., the number of copies of such data packet) that is to becommunicated during the uplink transmission, and/or another desiredparameter relating to the uplink transmission.

It is to be appreciated and understood that, while various aspects andembodiments of the disclosed subject matter are described herein withregard to determining and using the SINR and implicit NACK rateassociated with an uplink transmission of a communication device tocontrol (e.g., by the CMC 110) the group of parameters to improve therobustness of the uplink transmission, while also achieving a desirableefficiency of the uplink transmission, in accordance with the definedcommunication management criteria, the disclosed subject matter is notso limited. In accordance with various other aspects and embodiments ofthe disclosed subject matter, alternatively or additionally, the CMC 110can determine and/or utilize other communication condition metrics orparameters (e.g., a reference signal received power (RSRP) associatedwith a communication device, a reference signal received quality (RSRQ)associated with the communication device, and/or a channel qualityindicator (CQI) associated with the communication device) to controlvarious parameters (e.g., number of resource blocks, MCS value, amountof repetition of data packets, and/or another desired parameter) of thegroup of parameters associated with uplink transmission of acommunication device, such as communication device 104, to facilitateimproving the robustness of the uplink transmission to mitigate radiolink failure of the uplink transmission, while also achieving adesirable efficiency of the uplink transmission, in accordance with thedefined communication management criteria, and the systems, methods,techniques, and/or algorithms of the disclosed subject matter can bemodified or extended to utilize such other communication conditionmetrics or parameters, and such modifications or extensions of thesystems, methods, techniques, and/or algorithms of the disclosed subjectmatter are considered part of the disclosed subject matter.

The system 100 can include a resource block component 112 (RB COMP. 112)that can allocate respective resource blocks (e.g., PRBs) to respectivecommunication devices, such as communication device 104, for example, asrespectively controlled by the CMC 110. For instance, the CMC 110 candetermine that a certain number of resource blocks is to be allocated tothe communication device 104 for uplink transmission, and cancommunicate, to the resource block component 112, information (e.g.,instruction or control information) comprising or indicating a certainresource block parameter associated with (e.g., corresponding to orindicating) the certain number of resource blocks that is to beallocated to the communication device 104 for uplink transmission. Basedat least in part on such information, the resource block component 112can set or select the certain resource block parameter and/or canallocate the certain number of resource blocks to the communicationdevice 104 for uplink transmission and/or can communicate information(e.g., control, scheduling, or allocation information) regarding suchcertain resource block parameter and/or such allocation of resourceblocks to the communication device 104 via a desired communicationchannel (e.g., a control channel).

The system 100 also can comprise an MCS component 114 (MSC COMP. 114)that can facilitate selecting and implementing an MCS value (e.g., MCSindex value) of a set of MCS values, as determined and controlled by theCMC 110. For example, the CMC 110 can determine that a particular MCSvalue of the set of MCS values is to be utilized by the communicationdevice 104 for uplink transmission, in accordance with the definedcommunication management criteria, as more fully described herein. TheCMC 110 can communicate, to the MCS component 114, information (e.g.,instruction or control information) comprising or indicating theparticular MCS parameter associated with (e.g., corresponding to orindicating) the particular MCS value that is to be utilized by thecommunication device 104 for uplink transmission. Based at least in parton such information, the MCS component 114 can select or set theparticular MCS parameter and/or associated particular MCS value and/orcan communicate, to the communication device 104 via the desiredcommunication channel (e.g., the control channel), information (e.g.,control, scheduling, or allocation information) comprising or indicatingthe particular MCS parameter and/or the particular MCS value that thecommunication device 104 is to utilize for uplink transmission.

The MCS values (e.g., MCS index values) can relate to the number ofspatial streams employed for a data transmission (e.g., uplinktransmission), the modulation employed for the data transmission, and/orthe coding rate employed for the data transmission. Depending on the MCSvalue, the modulation can be, for example, binary phase shift keying(BPSK), quadrature phase shift keying (QPSK), 16-quadature amplitudemodulation (QAM), 64-QAM, and/or another desired modulation scheme(s).Also, depending on the MCS value, the coding rate can be, for example,½, ¾, ⅔, ⅚, and/or another desired coding rate. TABLE 1 comprises alisting of some example MCS index values and respectively associatedexample numbers of spatial streams, modulation schemes, and codingrates.

It is to be appreciated and understood that the MCS index values, numberof spatial streams, types of modulation, and coding rates, and therelationships or mappings between the MCS index values, number ofspatial streams, types of modulation, and coding rates in TABLE 1 arenon-limiting examples. In accordance with various other embodiments, asdesired, the MCS index values, number of spatial streams, types ofmodulation, and coding rates, and the relationships or mappings betweenthe MCS index values, number of spatial streams, types of modulation,and coding rates can be different from those presented in TABLE 1.

The system 100 further can include a packet repetition component 116(PKT REP. COMP. 116) that can facilitate selecting an amount ofrepetition of data packets for uplink transmission from communicationdevices, such as communication device 104, wherein the packet repetitioncan be managed by the CMC 110, in accordance with the definedcommunication management criteria, as more fully described herein. Forexample, in some instances, the CMC 110 can determine that a certainamount of repetition of data packets (or no repetition of data packets)is to be utilized by the communication device 104 for uplinktransmission, in accordance with the defined communication managementcriteria, and the CMC 110 can communicate, to the packet repetitioncomponent 116, information (e.g., instruction or control information)comprising or indicating the packet repetition parameter for the certainamount of repetition of data packets (or indicating the packetrepetition parameter for no repetition of data packets) that is to beutilized by the communication device 104 for uplink transmission. Basedat least in part on such information, the packet repetition component116 can facilitate selecting or setting the packet repetition parameterto have the certain amount of repetition of data packets (e.g., selector set a certain repetition number) (or can select or set the packetrepetition parameter for no repetition of data packets) and/or cancommunicate, to the communication device 104 via the desiredcommunication channel (e.g., the control channel), information (e.g.,control information) comprising or indicating the packet repetitionparameter and/or indicating the certain amount of repetition of datapackets that the communication device 104 is to utilize for uplinktransmission.

In some embodiments, the CMC 110, the resource block component 112, theMCS component 114, and/or the packet repetition component 116 can belocated in and/or part of the core network 107 and associated with(e.g., connected to) the RAN 108 of the communication network 102. Inother embodiments, the CMC 110, the resource block component 112, theMCS component 114, and/or the packet repetition component 116 can belocated in and/or part of another part of the communication network 102and associated with the RAN 108. In still other embodiments, the CMC110, the resource block component 112, the MCS component 114, and/or thepacket repetition component 116 can be located in and/or part of the RAN108, or they can be stand-alone components that can be associated withthe communication network 102 (e.g., the RAN 108 of the communicationnetwork 102).

The CMC 110 can receive communication-related information regardingcommunication conditions, including SINR and implicit NACK rate,relating to an uplink transmission of an uplink communication connectionbetween the communication device 104 and RAN 108. The CMC 110 cananalyze the communication-related information to determine the SINR, theimplicit NACK rate, and/or other communication conditions associatedwith the uplink transmission of the communication device 104. Based atleast in part the results of the analysis, the CMC 110 can determine oneor more communication condition metrics, including the SINR and/or theimplicit NACK rate, of the uplink transmission. The CMC 110 can control(e.g., manage) the group of parameters associated with the uplinktransmission for the communication device 104, based at least in part onthe results of an analysis (e.g., evaluation or comparison) of one ormore of the respective communication condition metrics and one or morerespectively applicable threshold values relating to the one or morerespective communication condition metrics and/or respective parametersof the group of parameters, in accordance with the defined communicationmanagement criteria.

For instance, based at least in part on the results of analyzing (e.g.,evaluating or comparing) a communication condition metric (e.g., theSINR or implicit NACK rate) relating to an uplink transmission and afirst threshold value (e.g., first threshold SINR or first thresholdNACK rate) relating to the communication condition metric of the uplinktransmission, the CMC 110 can determine whether the communicationcondition metric for the uplink transmission satisfies (e.g., meets orexceeds) the first threshold value, in accordance with the definedcommunication management criteria. The first threshold value can bedetermined and selected, in accordance with the defined communicationmanagement criteria, such that a communication condition metric thatsatisfies (e.g., meets or exceeds) the first threshold value can besufficiently robust to provide (e.g., suitably and/or reliably provide)desirable uplink transmission of information (e.g., ACK message, NACKmessage, and/or user data) from the communication device 104 to the RAN108. For example, with regard to SINR, the first threshold valuerelating to SINR can be set at a desired threshold value, such as −2.0decibels (dB), −1.0 dB, or another desired threshold value (e.g., −3.0dB, −4.0 dB, or −5.0 dB, . . . ), in accordance with the definedcommunication management criteria. As another example, with regard tothe implicit NACK rate, the first threshold value relating to theimplicit NACK rate can be set at a desired threshold value, such as10.0% or higher than 10.0% (e.g., 10.5%, 11.0%, 12.0%, . . . ), or evenlower than 10% (e.g., 9.0%, 9.5%, . . . ), in accordance with thedefined communication management criteria. It is to be appreciated andunderstood that these first threshold values for SINR and the implicitNACK rate are merely non-limiting example threshold values, and, inaccordance with various other embodiments, other threshold values forSINR and the implicit NACK rate can be utilized in accordance with thedisclosed subject matter.

It is to be appreciated and understood that, for reasons of brevity andclarity, various aspects and embodiments are described herein withregard to a communication condition metric (e.g., a SINR or an implicitNACK rate). However, additionally (e.g., in parallel or simultaneously,or serially, if desired), the CMC 110 can perform the operationsdescribed herein (e.g., determining each of the communication conditionmetrics, analyzing each of the communication condition metrics inrelation to the first (or other applicable) threshold value relating tosuch communication condition metric, controlling parameters of the groupof parameters, . . . ) with regard to multiple communication conditionmetrics (e.g., SINR, implicit NACK rate, and/or another communicationcondition metric) associated with an uplink transmission in relation torespective first (or other applicable) threshold values relating to therespective communication condition metrics, in accordance with thedefined communication management criteria.

If the CMC 110 determines that the communication condition metricsatisfies the first threshold value, and if the group of parameters(e.g., resource block parameter, MCS parameter, or packet repetitionparameter, . . . ) had not previously been modified to improve (e.g.,increase) the communication condition metric of the uplink transmission,the CMC 110 can determine that the group of parameters do not have to bemodified. If the group of parameters had previously been modified toimprove the communication condition metric (or another communicationcondition metric) of the uplink transmission, for example, by reducingthe number of resource blocks, reducing the MCS value, and/or increasingthe amount of repetition of data packets for the uplink transmission,the CMC 110 can determine whether the communication condition metric hassatisfied an applicable threshold value for a defined amount of time tofacilitate determining whether any parameter(s) of the group ofparameters is to be modified (e.g., to increase the number of resourceblocks, increase the MCS value, and/or reduce the amount of data packetrepetition), wherein the applicable threshold value can be the firstthreshold value or a second threshold value, whichever is applicable, inaccordance with the defined communication management criteria, as morefully described herein.

If, instead, the CMC 110 determines that the communication conditionmetric for the uplink transmission does not satisfy the first thresholdvalue, the CMC 110 can determine that at least one parameter (e.g., theresource block parameter, the MCS parameter, the packet repetitionparameter, and/or another parameter) of the group of parameters is to bemodified to facilitate improving the communication condition metric ofthe uplink transmission. In response to determining that at least oneparameter of the group of parameters is to be modified, the CMC 110 candetermine whether the number of resource blocks satisfies a definedminimum threshold number of resource blocks and whether the MCS valuesatisfies a defined minimum threshold MCS value, wherein the respectiveminimum threshold values for those parameters can be set in accordancewith the defined communication management criteria. One communicationmanagement criterion can indicate that the respective minimum thresholdvalues for those parameters are to be set to enable the uplinktransmission to at least have a desirable (e.g., minimally acceptable)level of efficiency, data rate, and/or other characteristic(s) for theuplink transmission, wherein, in some embodiments, this can be a defaultcommunication management criterion for determining and selecting therespective minimum threshold values for those parameters. In otherembodiments, in accordance with another communication managementcriterion, the CMC 110 can modify the respective minimum thresholdvalues for those parameters (e.g., to increase the respective minimumthreshold values) based at least in part on one or more other factors,such as, for example, the status of uplink ACK/NACK transmissions (e.g.,whether ACK/NACK transmissions are being segmented or buffered), as morefully described herein.

If the CMC 110 determines that the number of resource blocks does notsatisfy (e.g., does not meet or exceed) the defined minimum thresholdnumber of resource blocks and/or the MCS value does not satisfy thedefined minimum threshold MCS value, the CMC 110 can modify (e.g.,reduce) the resource block parameter to reduce the number of resourceblocks by a desired number of resource blocks (e.g., two resourceblocks, four resource blocks, or another desired number), such that thenumber of resource blocks will not be reduced below the defined minimumthreshold number of resource blocks, and/or can modify (e.g., reduce)the MCS parameter to reduce the MCS value by a defined number (e.g.,reduce the MCS value by two, four, or another desired number), such thatthe MCS value will not be reduced below the defined minimum thresholdMCS value. In some embodiments, the CMC 110 can adaptively determineand/or modify the step size (e.g., increase or decrease step size) ofreduction of the number of resource blocks and/or the step size of thereduction of the MCS value based at least in part on the relativeproximity of the SINR to first threshold value, in accordance with thedefined communication criteria, as more fully described herein.

In accordance with various embodiments, the CMC 110 can determine thatthe resource block parameter is to be modified to reduce the number ofresource blocks for the uplink transmission, without modifying the MCSparameter to reduce the MCS value for the uplink transmission; or theCMC 110 can determine that the MCS parameter is to be modified to reducethe MCS value for the uplink transmission, without modifying theresource block parameter to reduce the number of resource blocks for theuplink transmission; or the CMC 110 can determine that the resourceblock parameter is to be modified to reduce the number of resourceblocks and the MCS parameter is to be modified to reduce the MCS valuefor the uplink transmission, in accordance with (e.g., as specified by)the defined communication management criteria.

After modifying the resource block parameter and/or the MCS parameter,the CMC 110 can continue to monitor the communication-related conditions(e.g., the SINR, implicit NACK rate, and/or other conditions) associatedwith the uplink transmission to facilitate determining whetheradjustments (e.g., further adjustments) are to be made to any of theparameters of the group of parameters to facilitate improving thecommunication condition metric (e.g., SINR or implicit NACK rate), and,consequently, the robustness of the uplink transmission associated withthe communication device 104. If the CMC 110 determines that thecommunication condition metric satisfies the first threshold valuerelating to the communication condition metric, the CMC 110 candetermine that modification (e.g., further modification) of the resourceblock parameter and the MCS parameter is not to be performed at thattime, wherein the monitoring of the communication-related conditions cancontinue to determine whether the communication condition metriccontinues to satisfy the first threshold value, or satisfies theapplicable threshold value (which can be the first threshold value orthe second threshold value) for at least the defined amount of time, asmore fully described herein.

If, however, the number of resource blocks is determined to be at thedefined minimum threshold number of resource blocks, the CMC 110 candetermine that the number of resource blocks cannot be reduced anyfurther, and thus, the resource block parameter cannot be modified(e.g., reduced) any further to reduce the number of resource blocks. Ifthe MCS value is determined to be at the defined minimum threshold MCSvalue, the CMC 110 can determine that the MCS value cannot be reducedany further, and thus, the MCS parameter cannot be modified (e.g.,reduced) any further to reduce the MCS value.

If the resource block parameter and MCS parameter are not able to bemodified (e.g., reduced) to reduce the number of resource blocks orreduce the MCS value, the CMC 110 can evaluate the amount of repetitionof data packets (if any repetition) for the uplink transmissionassociated with the communication device 104 to determine whether thepacket repetition parameter is able to be modified (e.g., increased) toincrease the amount of repetition of data packets (e.g., ACK datapacket, NACK data packet, and/or packet of user data) via the uplinktransmission to facilitate improving (e.g., enhancing or increasing) thecommunication condition metric (e.g., SINR or implicit NACK rate), andconsequently, the robustness, of the uplink transmission, in accordancewith the defined communication management criteria. For instance, theCMC 110 can compare the amount of repetition of data packets (if anydata packet repetition) for the uplink transmission to a defined maximumthreshold amount of repetition of data packets for the uplinktransmission to determine whether the amount of repetition of datapackets satisfies (e.g., meets or is the same as) the defined maximumthreshold amount of repetition of data packets. Typically, if there hasbeen no repetition of data packets performed for the uplinktransmission, the CMC 110 can modify the packet repetition parameter toincrease the amount of repetition of data packets for the uplinktransmission (e.g., increase the number of copies of a particular datapacket to be communicated from the device 104 during the uplinktransmission), as the defined maximum threshold amount of repetition ofdata packets typically will not be satisfied under such circumstances.

If the CMC 110 determines that the amount of repetition of data packetssatisfies the defined maximum threshold amount of repetition of datapackets, the CMC 110 can determine that the packet repetition parameteris not able to be modified to increase the amount of repetition of datapackets for the uplink transmission, since the amount of repetition ofdata packets for the uplink transmission is already at the maximumamount of repetition of data packets permitted, in accordance with thedefined communication management criteria. If, however, the CMC 110determines that the amount of repetition of data packets for the uplinktransmission does not satisfy (e.g., is not at) the defined maximumthreshold amount of repetition of data packets for the uplinktransmission, the CMC 110 can determine that the packet repetitionparameter can be modified to increase the amount of repetition of datapackets for the uplink transmission by a defined amount (e.g., increaserepetition of a data packet by one, two, or another desired number ofdata packets), in accordance with the defined communication managementcriteria. Accordingly, the CMC 110 can modify the packet repetitionparameter to increase the amount of repetition of data packets for theuplink transmission by the defined amount of data packets.

For example, the CMC 110 can determine that the amount of repetition ofdata packets for the uplink transmission can be increased by one datapacket. That is, with respect to a data packet, if there had been onecopy of a data packet being communicated from the communication device104 during uplink transmission (such that there is no repetition), theCMC 110 can modify the packet repetition parameter to increase thenumber of copies of the data packet by a desired amount, such as one (atleast initially), such that the communication device 104 can communicatetwo copies of the data packet during the uplink transmission.

After modifying the packet repetition parameter, the CMC 110 cancontinue to monitor the communication-related conditions (e.g., theSINR, implicit NACK rate, and/or other communication-related conditions)associated with the uplink transmission for the device 104 to facilitatedetermining whether adjustments (e.g., further adjustments) are to bemade to the packet repetition parameter or any of the other parametersof the group of parameters to facilitate improving (e.g., enhancing orincreasing) the communication condition metric (e.g., SINR, implicitNACK rate, and/or other communication condition metric), and,consequently, the robustness of the uplink transmission associated withthe communication device 104. If analysis of communication-related datarelating to the communication-related conditions associated with theuplink transmission indicates that the communication condition metric isstill not satisfying the first threshold value relating to thatcommunication condition metric, the CMC 110 can continue (e.g.,iteratively continue) to modify the packet repetition parameter tofurther increase the amount of repetition of data packets for the uplinktransmission either until the communication condition metric satisfiesthe first threshold value or until the defined maximum threshold amountof repetition of data packets has been satisfied (e.g., reached). If theCMC 110 determines that the communication condition metric has satisfiedthe first threshold value, or determines that the defined maximumthreshold amount of repetition of data packets has been satisfied, theCMC 110 can determine that the amount of repetition of data packets forthe uplink transmission is not to be increased any further at this time.

As disclosed, the CMC 110 can continue to monitor thecommunication-related conditions (e.g., SINR, implicit NACK rate, and/orother communication-related conditions) associated with the uplinktransmission for the device 104. If the CMC 110 determines that acommunication condition metric (e.g., SINR or implicit NACK rate)associated with the uplink transmission has satisfied the applicablethreshold value relating to such communication condition metric for atleast the defined amount of time, the CMC 110 can determine that one ormore of the parameters of the group of parameters are to be modified toimprove the efficiency of the uplink transmission while stillmaintaining a desirable communication condition metric value (e.g.,SINR) and/or another desired communication condition metric value (e.g.,implicit NACK rate), in accordance with the defined communicationmanagement criteria. For instance, if there has been no repetition ofdata packets performed (or if repetition of data packets has been ceasedor removed), and if the CMC 110 determines that the communicationcondition metric associated with the uplink transmission has satisfiedthe applicable threshold value for at least the defined amount of time,the CMC 110 can determine that the resource block parameter is to bemodified (e.g., increased) to increase the number of resource blocks bya desired amount (e.g., increase the number of resource blocks by two,four, or other desired number of resource blocks) for the uplinktransmission and/or the MCS parameter is to be modified (e.g.,increased) to increase the MCS value (e.g., increase the MCS value bytwo, four, or other desired number) for the uplink transmission.

If data packet repetition has been performed for the uplinktransmission, and if the CMC 110 determines that the communicationcondition metric associated with the uplink transmission has satisfiedthe applicable threshold value for at least the defined amount of time,the CMC 110 can determine that the packet repetition parameter is to bemodified (e.g., decreased) to decrease the amount of repetition of datapackets by a desired amount (e.g., one data packet copy) for the uplinktransmission (e.g., to reduce the number of copies of a particular datapacket to be communicated via the uplink transmission). The CMC 110 cancontinue to monitor the communication-related conditions and can makefurther modifications to one or more of the parameters (e.g., toincrease the number of resource blocks, to increase the MCS value, or todecrease the amount of repetition of data packets), for example, if thecommunication condition metric is determined to satisfy (e.g., continuesto satisfy) the applicable threshold value for a defined amount of time(e.g., another defined amount of time, since the last parametermodification), in accordance with the defined communication managementcriteria.

With further regard to the repetition of data packets, in someembodiments, the CMC 110 can associate, add, or apply a tag to datapackets (e.g., repetitive data packets) of a message (e.g., an ACKmessage or a NACK message) carried in the uplink transmission, whereinthe tag can indicate to which downlink transmission the messagerepetition (e.g., packet repetition of an ACK or NACK message) appliesor is related. For instance, for ACK and NACK messages on PUCCH, theresometimes can be a time limitation, such as an n+x time slot, for thecommunication of such messages, wherein n and x can be respective numbervalues. For the repetition of the data packets of the message to berecognized by the receiver (e.g., base station of the RAN 108, orcommunication network 102) of the message, the CMC 110 can associate,add, or apply the tag to the data packets (e.g., repetitive datapackets) of the message to indicate the downlink transmission (e.g., thedata in the downlink message) to which the uplink message repetition(e.g., ACK or NACK message repetition) applies or relates.

In some embodiments, in accordance with certain communication managementcriteria, the applicable threshold value relating to a particularcommunication condition metric can be the second threshold valuerelating to that particular communication condition metric, whichtypically can be a lower value (e.g., a lower SINR, or a lower implicitNACK rate) than the first threshold value relating to that particularcommunication condition metric, but still can be a high enough value toensure that the uplink transmission has a desirable (e.g., suitable oracceptable) communication condition metric value (e.g., SINR, orimplicit NACK rate) and desirable robustness. In other embodiments, thecommunication management criteria can be structured to indicate that theapplicable threshold value relating to a particular communicationcondition metric is to be the same as the first threshold value relatingto that particular communication condition metric. By not modifying theparameters for the uplink transmission unless the particularcommunication condition metric has satisfied the applicable thresholdvalue for at least the defined amount of time, the CMC 110 can keep fromperforming too many parameter adjustments due to the particularcommunication condition metric repeatedly swinging between being above athreshold value and below the threshold value relating to thatcommunication condition metric in response to the parameter adjustments,and can thereby maintain stability of the uplink transmission.

With further regard to the defined minimum threshold number of resourceblocks and the defined minimum threshold MCS value for uplinktransmission, the CMC 110 (or another component of the system 100) candetermine, set, and/or adjust (e.g., adaptively determine, set, and/oradjust) those respective threshold values based at least in part on oneor more factors, in accordance with the defined communication managementcriteria. For instance, one communication management criterion canindicate that the defined minimum threshold number of resource blocksand the defined minimum threshold MCS value are to be determined,selected, or set to enable the uplink transmission to at least have adesirable (e.g., minimally acceptable) level of efficiency, data rate,and/or other characteristic(s) for the uplink transmission. In someembodiments, this communication management criterion can be the defaultcommunication management criterion for determining, selecting, orsetting the defined minimum threshold number of resource blocks and thedefined minimum threshold MCS value for uplink transmission.

In other embodiments, in accordance with another communicationmanagement criterion, the CMC 110 can modify the defined minimumthreshold number of resource blocks and the defined minimum thresholdMCS value for uplink transmission (e.g., to increase the respectiveminimum threshold values) based at least in part on one or more otherfactors, such as, for example, the status of uplink ACK/NACKtransmissions (e.g., whether ACK/NACK transmissions are being segmentedor buffered). For example, there can be instances where the CMC 110 (oranother component of the system 100) can determine that a currentminimum threshold number of resource blocks and/or a current minimumthreshold MCS value (e.g., based at least in part on the defaultcommunication management criterion) can or may result in ACKtransmission or NACK transmissions for uplink being segmented intomultiple segments because there are not sufficient resources (e.g.,resource blocks) to communication the ACK or NACK messages withoutsegmenting the messages and/or buffered (e.g., buffered or backlogged ina buffer memory of the device 104) because there are not sufficientresources to communication the ACK or NACK messages at desired times. Tomitigate (e.g., reduce, minimize, or eliminate) the segmenting orbuffering of ACK and NACK messages for uplink transmission, the CMC 110can determine (e.g., adaptively determine) a modification for thedefined minimum threshold number of resource blocks to increase thethreshold number of blocks for the minimum threshold number of resourceblocks to a desired higher number for uplink transmission and/ordetermine (e.g., adaptively determine) a modification for the definedminimum threshold MCS value to increase the threshold MCS value to a forthe defined minimum threshold MCS value to a higher MCS value based atleast in part on a result of the status of uplink ACK/NACK transmissions(e.g., whether ACK/NACK transmissions are being segmented or buffered).

With further regard to the defined maximum threshold amount ofrepetition of data packets for the uplink transmission, the CMC 110 (oranother component of the system 100) can determine, set, and/or adjust(e.g., adaptively determine, set, and/or adjust) the defined maximumthreshold amount of repetition of data packets for uplink transmissionfor the device 104 based at least in part on one or more factors (e.g.,number of UEs associated with the RAN 108 or communication network 102,respective quality of service (QoS) and/or quality of experience (QoE)specifications of the respective communication devices, and/or anotherfactor), in accordance with the defined communication managementcriteria. For example, if the CMC 110 determines that there arerelatively few communication devices associated with the RAN 108 orcommunication network 102 overall, and/or the overall QoS, QoE, and/orresource demands of such communication devices is relatively low, theCMC 110 can determine (e.g., adaptively determine) that the definedmaximum threshold amount of repetition of data packets for uplinktransmission for the device 104 can be a relatively higher amount ofdata packet repetition (e.g., such that a relatively higher number ofcopies of a particular data packet can be transmitted via the uplinktransmission) without undesirably impacting the data communications,QoS, and/or QoE of the other communication devices associated with theRAN 108 or communication network 102. In such instances, the CMC 110 canaccordingly set or adjust the defined maximum threshold amount ofrepetition of data packets for uplink transmission for the communicationdevice 104 to a relatively higher amount (e.g., a relatively highernumber of copies of a particular data packet).

However, if the CMC 110 determines that there is a relatively highnumber of communication devices associated with the RAN 108 orcommunication network 102, and/or the overall QoS, QoE, and/or resourcedemands of such communication devices is relatively high, the CMC 110can determine (e.g., adaptively determine) that the defined maximumthreshold amount of repetition of data packets for uplink transmissionfor the communication device 104 is to be relatively lower amount ofdata packet repetition (e.g., such that a relatively lower number ofcopies of a particular data packet can be transmitted via the uplinktransmission) without undesirably impacting the data communications,QoS, and/or QoE of the other communication devices associated with theRAN 108 or communication network 102. In such instances, the CMC 110 canaccordingly set or adjust the defined maximum threshold amount ofrepetition of data packets for uplink transmission for the communicationdevice 104 to a relatively lower amount (e.g., a relatively lower numberof copies of a particular data packet).

With further regard to step sizes, in some embodiments, the CMC 110 candetermine, set, and/or adjust (e.g., adaptively determine, set, and/oradjust) a step size (e.g., an amount of change) of a modification of aparameter (e.g., resource block parameter, MCS parameter, and/or packetrepetition parameter, . . . ) based at least in part on a communicationcondition metric (e.g., SINR or implicit NACK rate) associated with theuplink transmission in relation to the first threshold value relating tothat communication condition metric or other applicable threshold valuerelating to that communication condition metric (whichever thresholdvalue is applicable, in accordance with the defined communicationmanagement criteria). For example, the CMC 110 can analyzecommunication-related information relating to the communicationcondition metric for the uplink transmission of the device 104 todetermine the communication condition metric and to evaluate thecommunication condition metric in relation to the first threshold valueor other applicable threshold value relating to that communicationcondition metric. If, based at least in part on the results of theanalysis and the evaluation, the CMC 110 determines that thecommunication condition metric is lower than the first threshold value,but is relatively close to the first threshold value, the CMC 110 candetermine that a step size for a parameter(s) (e.g., resource blockparameter, MCS parameter, and/or packet repetition parameter, . . . ) isto be set or adjusted to be relatively smaller. For instance, if thestep size for the resource block parameter had been set or controlled todecrease the number of resource blocks by four blocks when thecommunication condition metric is determined to not be high enough tosatisfy the first threshold value, in response to determining that thecommunication condition metric is (still) lower than the first thresholdvalue, but is relatively close to the first threshold value, the CMC 110can determine that the step size for the resource block parameter is tobe reduced such that the modification of the resource block parameterwill decrease the number of resource blocks by two resource blocks or byanother number (e.g., three or one) that is lower than four resourceblocks, in accordance with the defined communication managementcriteria.

If, however, based at least in part on the results of the analysis andthe evaluation, the CMC 110 determines that the communication conditionmetric is lower than the first threshold value and is still relativelyfar away from the first threshold value, the CMC 110 can determine thata step size for a parameter(s) (e.g., resource block parameter, MCSparameter, and/or packet repetition parameter, . . . ) is to bemaintained at its current step size, is to be set or adjusted to berelatively larger, or is to be set or adjusted to be relatively smaller(but not adjusted to reduce the step size as much as an instance wherethe communication condition metric is relatively close to the firstthreshold value). For instance, if the step size for the resource blockparameter had been set or controlled to decrease the number of resourceblocks by four blocks when the communication condition metric isdetermined to not be high enough to satisfy the first threshold value,in response to determining that the communication condition metric isstill lower than the first threshold value and is relatively far awayfrom the first threshold value, the CMC 110 can determine that the stepsize for the resource block parameter is to be maintained at its currentstep size of four resource blocks, is to be set or adjusted to berelatively larger (e.g., a step size of five resource blocks), or is tobe set or adjusted to be relatively smaller (e.g., three resourceblocks, but not adjusted to reduce the step size as much as a situationwhere the communication condition metric is relatively close to thefirst threshold value).

In a similar manner, the CMC 110 can determine whether the step size ofthe MCS value and/or the step size with regard to the amount ofrepetition of data packets are to adjusted (e.g., adaptively adjusted)based at least in part on the relative closeness of the communicationcondition metric of the uplink transmission for the device 104 to thefirst threshold value or other applicable threshold value, in accordancewith the defined communication management criteria. For example, if,based at least in part on the results of the analysis and theevaluation, the CMC 110 determines that the communication conditionmetric is lower than the first threshold value, but is relatively closeto the first threshold value, the CMC 110 can determine that a step sizefor the MCS parameter is to be set or adjusted to be relatively smaller,such that, if the step size for the resource block parameter had beenset or controlled to decrease the MCS value by four when thecommunication condition metric is determined to not be high enough tosatisfy the first threshold value, in response to determining that thecommunication condition metric is (still) lower than the first thresholdvalue, but is relatively close to the first threshold value, the CMC 110can determine that the step size for the MCS parameter is to be reducedsuch that the modification of the MCS parameter will decrease the MCSvalue by two or by another number (e.g., three or one) that is lowerthan four, in accordance with the defined communication managementcriteria.

In some embodiments, the communication device 104 can comprise acommunication management agent component (CMAC) 118 that can determineand/or utilize resource blocks, an MCS value, and/or repetition of datapackets based at least in part on parameter-related information (e.g.,control, scheduling, and/or allocation information) received from theCMC 110. For example, the CMAC 118 can receive the parameter-relatedinformation from the CMC 110 via a downlink communication channel (e.g.,downlink control channel). The CMAC 118 can analyze theparameter-related information, wherein the parameter-related informationcan indicate or specify the resource block parameter and/or the numberof resource blocks allocated to the communication device 104 for theuplink transmission; the MCS parameter and/or the MCS value to beutilized for the uplink transmission, and/or the number of spatialstreams, the modulation, and/or the coding rate to be utilized for theuplink transmission; and/or the packet repetition parameter and/orwhether repetition of data packets is to be utilized for the uplinktransmission, and, if so, the amount of repetition of data packets(e.g., two copies of a data packet, or three copies of the data packet,. . . ) to be utilized.

Based at least in part on the results of the analysis of theparameter-related information, the CMAC 118 can determine the resourceblock parameter and/or the number of resource blocks allocated to thecommunication device 104 for the uplink transmission; the MCS parameterand/or the MCS value to be utilized for the uplink transmission, and/orthe number of spatial streams, the modulation, and/or the coding rate tobe utilized for the uplink transmission; and/or the packet repetitionparameter and/or whether repetition of data packets is to be utilizedfor the uplink transmission, and, if so, the amount of repetition ofdata packets (e.g., two copies of a data packet, or three copies of thedata packet, . . . ) to be utilized. The CMAC 118 can control operationof the communication device 104 during the uplink transmission toutilize the allocated number of resource blocks, in accordance with theresource block parameter; to utilize the desired MCS value andaccordingly the desired number of spatial streams, the desiredmodulation, and/or the desired coding rate, in accordance with the MCSparameter; and/or to utilize a desired amount of repetition of datapackets or no repetition of data packets (as appropriate), in accordancewith the packet repetition parameter.

The disclosed subject matter, by employing the CMC 110, can improve(e.g., increase) SINR, implicit NACK rate, and/or other uplinktransmission-related metrics (e.g., RSRP, RSRQ, and/or CQI) androbustness of the uplink transmission associated with the communicationdevice 104, and can reduce radio link failure of the uplinktransmission, while also maintaining a desirable level of efficiency,data rate, and/or other characteristic(s) for the uplink transmission.Accordingly, the disclosed subject matter, by employing the CMC 110,also can improve connectivity stability (e.g., 5G NR connectivitystability), reduce the amount of signaling utilized with regard to theuplink transmission (e.g., reduce or minimize additional signaling dueto the communication device having to set up a 5G NR leg (e.g.,secondary leg) for the data plane again after radio link failure, sinceradio link failure can be reduced by the disclosed subject matter),improve (e.g., increase) data throughput (e.g., data throughput of theuplink transmission and downlink transmission), and improve (e.g.,increase or enhance) other key performance indicators (KPIs).

Referring to FIG. 2, FIG. 2 illustrates a block diagram of anotherexample, non-limiting system 200 that can control a group of parametersassociated with an uplink transmission of a communication deviceassociated with a communication network to facilitate improvingcommunication condition metrics (e.g., the SINR and/or implicit NACKrate) and robustness of the uplink transmission, in accordance withvarious aspects and embodiments of the disclosed subject matter. Thesystem 200 can comprise the communication device 104, the RAN 108, theCMC 110, the resource block component 112, the MCS component 114, andthe packet repetition component 116.

The CMC 110 can control the number of resource blocks allocated tothe communication device 104 to facilitate improving a communicationcondition metric (e.g., the SINR or implicit NACK rate) and robustnessassociated with the uplink transmission 202 (e.g., by reducing thenumber of resource blocks allocated to the communication device 104 whenthe communication condition metric is below the first threshold valuerelating to the communication condition metric or other applicablethreshold value relating to the communication condition metric), whilealso achieving a desired level of efficiency of the uplink transmission202 (e.g., by maintaining at least a desired minimum number of resourceblocks for the uplink transmission 202), in accordance with the definedcommunication management criteria, as more fully described herein.

Also, in connection with controlling the group of parameters, the CMC110 can control operation of the MCS component 114 to determine, select,or modify an MCS value 210 (e.g., MCS index value) to control or modifya number (no.) of spatial streams 212 (e.g., one spatial stream, twospatial streams, . . . ) for the uplink transmission 202, the modulation214 (e.g., BPSK, QPSK, QAM, 64-QAM, . . . ) utilized for the uplinktransmission 202, and/or the coding rate 216 (e.g., ½, ¾, ⅔, ⅚, . . . )utilized for the uplink transmission 202, in accordance with the definedcommunication management criteria, including applicable threshold values(e.g., defined minimum threshold MCS value), to facilitate improving thecommunication condition metric and robustness associated with the uplinktransmission 202 (e.g., by reducing the MCS value associated with theuplink transmission 202 for the communication device 104 when acommunication condition metric is below a first threshold value or otherapplicable threshold value relating to that communication conditionmetric).

Further, in connection with controlling the group of parameters, the CMC110 can control operation of the packet repetition component 116 todetermine, select, or modify a repetition value 218 (e.g., repetitionparameter value) and, correspondingly, an amount of repetition ofrespective data packets, such as a number of copies of a data packet 220(e.g., one data packet (e.g., no repetition of the data packet), twocopies of the data packet, or three copies of the data packet, . . . ),in accordance with the defined communication management criteria,including applicable threshold values (e.g., defined maximum thresholdamount of repetition of data packets), to facilitate improving thecommunication condition metrics and robustness associated with theuplink transmission 202 (e.g., by increasing the amount of repetition ofrespective data packets associated with the uplink transmission 202 whena communication condition metric is below a first threshold value orother applicable threshold value relating to the communication conditionmetric (and the number of resource blocks and MCS value are not able tobe reduced any further)).

FIG. 4 illustrates a flow diagram of an example, non-limiting method 400that can control a group of parameters associated with an uplinktransmission of a communication device associated with a communicationnetwork to facilitate improving the communication condition metrics androbustness of the uplink transmission, in accordance with variousaspects and embodiments of the disclosed subject matter. The method 400can be implemented by a system that can comprise a CMC of or associatedwith the communication network, a processor component, a data store,and/or another component(s). Alternatively, or additionally, amachine-readable storage medium can comprise executable instructionsthat, when executed by a processor, facilitate performance of theoperations of the method 400.

At 402, a communication condition metric of an uplink communicationconnection associated with a communication device can be determined. TheCMC can receive and analyze communication-related data regarding anuplink communication connection (e.g., a wireless uplink communicationconnection) associated with the communication device. Based at least inpart on the results of the analysis, the CMC can determine thecommunication condition metric (e.g., the SINR, the implicit NACK rate,or other desired communication condition metric) of the uplinkcommunication connection.

At 404, a group of parameters associated with the uplink communicationconnection can be controlled, based at least in part on a result ofanalyzing the communication condition metric and a first threshold valuerelating to the communication condition metric, to facilitate improvingthe communication condition metric of an uplink transmission. The CMCcan analyze the communication condition metric and the first thresholdvalue relating to the communication condition metric. The firstthreshold value relating to the communication condition metric can bedetermined and set (e.g., by the CMC), based at least in part on thedefined communication management criteria, to facilitate enhancing(e.g., improving) the robustness of the uplink transmission, providing adesirable communication condition metric (e.g., SINR or implicit NACKrate) for the uplink transmission, and reducing radio link failure ofthe uplink transmission. Based at least in part on the results ofanalyzing the communication condition metric and the first thresholdvalue, the CMC can control the group of parameters (e.g., communicationparameters, such as uplink and/or resource parameters) associated withthe uplink communication connection. The group of parameters cancomprise, for example, the resource block parameter relating to thenumber of resource blocks (e.g., PRBs) utilized during the uplinktransmission, the MCS parameter relating to an MCS value utilized duringthe uplink transmission, the packet repetition parameter relating to theamount of repetition of transmission of a particular data packet (e.g.,the number of copies of such data packet) that is to be communicatedduring the uplink transmission, and/or another desired parameterrelating to the uplink transmission.

For instance, as more fully described herein, in response to determiningthat the communication condition metric does not satisfy the firstthreshold value (e.g., the communication condition metric does not meetor exceed the first threshold communication condition metric value), theCMC can modify (e.g., adjust or reduce) the resource block parameter toreduce the number of resource blocks and/or modify the MCS parameter toreduce the MCS value to facilitate improving (e.g., increasing orenhancing) the communication condition metric of the uplink transmissionand achieving a communication condition metric that satisfies the firstthreshold value, in accordance with the defined communication managementcriteria. If the number of resource blocks and the MCS value are notable to be reduced any further (e.g., due to respective thresholdminimum levels for the resource blocks and the MCS value being reached(e.g., being satisfied)) to achieve a communication condition metricthat satisfies the first threshold value, the CMC can modify (e.g.,adjust or increase) the packet repetition parameter to increase theamount of repetition of transmission of a particular data packet (e.g.,up to a maximum repetition number for repetition of the transmission ofsuch data packet) to facilitate improving the communication conditionmetric of the uplink transmission and achieving a communicationcondition metric that satisfies the first threshold value, in accordancewith the defined communication management criteria.

Also, as more fully described herein, the CMC can control the group ofparameters to increase the number of resource blocks and/or the MCSvalue, and/or reduce the amount of repetition of transmission of aparticular data packet, for the uplink transmission, in response todetermining that the communication condition metric has satisfied anapplicable threshold value relating to the communication conditionmetric (e.g., the first threshold value or a second threshold valuerelating to the communication condition metric) for at least a definedperiod of time (e.g., a defined amount of time), wherein the CMC candetermine the applicable threshold value to use based at least in parton the defined communication management criteria.

The method 500can be implemented by a system that can comprise a CMC of or associatedwith the communication network, a processor component, a data store,and/or another component(s). Alternatively, or additionally, amachine-readable storage medium can comprise executable instructionsthat, when executed by a processor, facilitate performance of theoperations of the method 500.

At 502, communication conditions, including a SINR and/or implicit NACKrate, of an uplink transmission associated with a communication devicecan be monitored. The CMC and/or other components of the system (e.g.,monitor component and/or sensors of the system) can monitor an uplinkcommunication connection associated with the communication device.During the monitoring, the CMC can receive and analyze thecommunication-related data associated with (e.g., relating to) theuplink transmission.

At 504, a communication condition metric of the uplink transmission canbe determined based at least in part on a result of analyzing thecommunication-related data associated with the uplink transmission. TheCMC can analyze the communication-related data, and based at least inpart on the result of the analysis, can determine the communicationcondition metric (e.g., SINR, implicit NACK rate, or other desiredcommunication condition metric) associated with the uplink transmission.

At 506, a determination can be made regarding whether the communicationcondition metric satisfies a first threshold value relating to thecommunication condition metric. The CMC can analyze the communicationcondition metric and the first threshold value. The first thresholdvalue (e.g., first threshold SINR, or first threshold implicit NACKrate) can be determined and set (e.g., by the CMC), based at least inpart on the defined communication management criteria, to facilitateenhancing (e.g., improving) the robustness of the uplink transmission,providing a desirable communication condition metric for the uplinktransmission, and/or reducing radio link failure of the uplinktransmission. Based at least in part on the results of analyzing thecommunication condition metric and the first threshold value, the CMCcan determine whether the communication condition metric satisfies thefirst threshold value.

In response to determining that the communication condition metricsatisfies the first threshold value, at 508, a determination can be maderegarding whether a group of parameters associated with the uplinktransmission had previously been modified to improve (e.g., increase)the communication condition metric (or other communication conditionmetric) of the uplink transmission. The group of parameters cancomprise, for example, the resource block parameter relating to thenumber of resource blocks (e.g., PRBs) utilized during the uplinktransmission, the MCS parameter relating to an MCS value utilized duringthe uplink transmission, the packet repetition parameter relating to theamount of repetition of transmission of a particular data packet that isto be communicated during the uplink transmission, and/or anotherdesired parameter. In response to determining that the communicationcondition metric satisfies the first threshold value, the CMC candetermine whether the group of parameters (e.g., resource blockparameter, MCS parameter, packet repetition parameter, and/or otherdesired parameter) associated with the uplink transmission hadpreviously been modified to improve (e.g., increase) the communicationcondition metric (or other communication condition metric) of the uplinkcommunication connection. For instance, the CMC can determine whetherthe resource block parameter had been modified to reduce the number ofresource blocks utilized for the uplink communication connection and/orthe MCS parameter had been modified to reduce the MCS value utilized forthe uplink communication connection, and/or whether the packetrepetition parameter had been modified to increase the number of copiesof a data packet that are transmitted via the uplink communicationconnection, to improve the communication condition metric (or othercommunication condition metric) of the uplink transmission.

In response to determining that the group of parameters associated withthe uplink transmission had not previously been modified to improve thecommunication condition metric (or other communication condition metric)of the uplink transmission, at 510, it can be determined that the groupof parameters associated with the uplink transmission do not have to bemodified. In response to determining that the communication conditionmetric satisfies the first threshold value, and in response todetermining that the group of parameters associated with the uplinktransmission had not previously been modified to improve thecommunication condition metric (or other communication condition metric)of the uplink transmission, the CMC can determine that the group ofparameters do not have to be modified. At this point, the method 500 canproceed from reference numeral 510 to reference numeral 502, wherein themethod 500 can proceed from that point to monitor the communicationconditions, including the SINR and/or implicit NACK rate, of the uplinktransmission and continue from that point to perform other operations ofthe method 500.

If, at reference numeral 508, it is determined that the group ofparameters associated with the uplink transmission had previously beenmodified to improve (e.g., increase) the communication condition metric(or other communication condition metric) of the uplink transmission,the method 500 can proceed to reference point A, wherein, as depicted inFIG. 6, the method 500 can proceed from reference point A to referencenumeral 518 to facilitate determining whether one or more parameters ofthe group of parameters are to be modified to increase the number ofresource blocks, increase the MCS value, or reduce the amount ofrepetition of data packets for the uplink transmission, as more fullydescribed below with regard to FIG. 6.

Referring again to reference numeral 506, if, at 506, it is determinedthat the communication condition metric for the uplink transmission doesnot satisfy the first threshold value, at 512, it can be determined thatat least one parameter of the group of parameters associated with theuplink transmission is to be modified. In response to determining thatthe communication condition metric does not satisfy the first thresholdvalue, the CMC can determine that at least one parameter (e.g., theresource block parameter, the MCS parameter, the packet repetitionparameter, and/or another parameter) of the group of parameters is to bemodified to facilitate improving the communication condition metric ofthe uplink transmission.

At 514, a determination can be made regarding whether the number ofresource blocks (RBs) satisfies a defined minimum threshold number ofresource blocks and whether the MCS value satisfies a defined minimumthreshold MCS value. In response to determining that at least oneparameter of the group of parameters is to be modified, the CMC candetermine whether the number of resource blocks satisfies the definedminimum threshold number of resource blocks and whether the MCS valuesatisfies the defined minimum threshold MCS value. If the number ofresource blocks is at the defined minimum threshold number of resourceblocks, the CMC can determine that the number of resource blocks cannotbe reduced any further, and thus, the resource block parameter cannot bemodified (e.g., reduced) any further to reduce the number of resourceblocks. If the MCS value is at the defined minimum threshold MCS value,the CMC can determine that the MCS value cannot be reduced any further,and thus, the MCS parameter cannot be modified (e.g., reduced) anyfurther to reduce the MCS value.

In response to determining that the number of resource blocks satisfiesthe defined minimum threshold number of resource blocks and determiningthat the MCS value satisfies the defined minimum threshold MCS value,the method 500 can proceed to reference point B, wherein, as illustratedin FIG. 7, the method 500 can proceed from reference point B toreference numeral 526 to facilitate evaluating another parameter(s)(e.g., packet repetition parameter) and determining whether such otherparameter(s) can be modified, since the resource block parameter and theMCS parameter are not able to be modified (e.g., reduced) at this point.In some embodiments, the method 500 of FIG. 7 can proceed from referencepoint B, as more fully described herein with respect to FIG. 7.

If, at reference numeral 514, it is determined that the number ofresource blocks does not satisfy the defined minimum threshold number ofresource blocks and/or the MCS value does not satisfy the definedminimum threshold MCS value, at 516, the resource block parameter can bemodified to reduce the number of resource blocks and/or the MCSparameter can be modified to reduce the MCS value. If the CMC determinesthat the number of resource blocks does not satisfy the defined minimumthreshold number of resource blocks and/or the MCS value does notsatisfy the defined minimum threshold MCS value, the CMC can modify(e.g., reduce) the resource block parameter to reduce the number ofresource blocks by a desired number of resource blocks (e.g., tworesource blocks, four resource blocks, or another desired number) (thatwill not reduce the number of resource blocks below the defined minimumthreshold number of resource blocks) and/or can modify (e.g., reduce)the MCS parameter to reduce the MCS value by a defined number (e.g.,reduce the MCS value by two, four, or another desired number) (that willnot reduce the MCS value below the defined minimum threshold MCS value).At this point, the method 500 can proceed from reference numeral 516 toreference numeral 502, wherein the method 500 can proceed from thatpoint to monitor the communication conditions, including the SINR and/orimplicit NACK rate, of the uplink transmission associated with thecommunication device and continue from that point to perform otheroperations of the method 500.

FIG. 6 illustrates a flow diagram of a portion of the example,non-limiting method 500 that can control the group of parametersassociated with the uplink transmission of the communication device,wherein the communication condition metric has satisfied at least thefirst threshold value relating to the communication condition metric, inaccordance with various aspects and embodiments of the disclosed subjectmatter.

In some embodiments, the portion of the method 500 with respect to FIG.6 can proceed from reference point A of the method 500 as described withregard to FIG. 5. At this point, it already can be determined that thecommunication condition metric of the uplink transmission satisfies thefirst threshold value and that one or more parameters of the group ofparameters had previously been modified to, for example, reduce thenumber of resource blocks used, reduce the MCS value, and/or increasethe amount of repetition of transmission of data packets for the uplinktransmission. This portion of the method 500 can be employed todetermine whether one or more parameters of the group of parameters areto be modified to, for example, increase the number of resource blocksused, increase the MCS value, and/or decrease the amount of repetitionof transmission of data packets for the uplink transmission, since thecommunication condition metric of the uplink transmission at leastsatisfies the first threshold value.

At 518, a determination can be made regarding whether the communicationcondition metric has satisfied an applicable threshold value relating tothe communication condition metric for at least a defined amount oftime. The CMC can determine whether the communication condition metrichas satisfied the applicable threshold value relating to thecommunication condition metric for at least the defined amount of time,in accordance with the defined communication management criteria. Insome embodiments, the applicable threshold value can be the same as thefirst threshold value, and, in other embodiments, the applicablethreshold value can be a second (e.g., different) threshold valuerelating to the communication condition metric. The CMC also candetermine and set the defined amount of time in accordance with thedefined communication management criteria.

In response to determining that the communication condition metric ofthe uplink transmission has not satisfied the applicable threshold valuefor at least the defined amount of time, at 520, it can be determinedthat the group of parameters is not to be modified. In response todetermining that the communication condition metric has not satisfiedthe applicable threshold value for at least the defined amount of time,the CMC can determine that the group of parameters is not to be modifiedat this time. At this point, the method 500 can proceed from referencenumeral 520 to reference point C, wherein the method 500 can proceedfrom reference point C to reference numeral 502 with respect to FIG. 5,wherein the method 500 can proceed from that point to monitor thecommunication conditions, including the SINR and/or the implicit NACKrate, of the uplink transmission of the communication device and cancontinue from that point to perform other operations of the method 500,as appropriate.

If, at reference numeral 518, it is determined that the communicationcondition metric of the uplink transmission has satisfied the applicablethreshold value for at least the defined amount of time, at 522, it canbe determined that at least one parameter of the group of parameters canbe modified. At 524, the at least one parameter (e.g., the resourceblock parameter, the MCS parameter, and/or the packet repetitionparameter) of the group of parameters can be modified.

In response to determining that the communication condition metric ofthe uplink transmission has satisfied the applicable threshold value forat least the defined amount of time, the CMC can determine that at leastone parameter of the group of parameters can be modified, for example,to increase the number of resource blocks utilized for the uplinktransmission, increase the MCS value for the uplink transmission, and/orreduce the amount of repetition of data packets for the uplinktransmission. For instance, if repetition of data packets had previouslybeen increased for the uplink transmission, the CMC can determine thatthe packet repetition parameter can be modified (e.g., reduced) todecrease the amount of repetition of data packets used for the uplinktransmission by a desired amount (e.g., decrease the number of copies ofa data packet by one, by two, or by another desired number). As anotherexample, if the number of resource blocks had previously been decreasedand/or the MCS value had previously been decreased (and if there is norepetition of data packets for the uplink transmission), the CMC candetermine that the resource block parameter can be modified (e.g.,increased) to increase the number of resource blocks used for the uplinktransmission by a defined number of resource blocks (e.g., increase thenumber of resource blocks by two, four, or other desired number ofresource blocks) and/or the MCS parameter can be modified (e.g.,increased) to increase the MCS value used for the uplink transmission bya defined amount (e.g., increase the MCS value by two, four, or otherdesired number), in accordance with the defined communication managementcriteria. The CMC can modify the at least one parameter of the group ofparameters.

At this point, the method 500 can proceed from reference numeral 524 toreference point D, wherein the method 500 can proceed from referencepoint D to reference numeral 502 with respect to FIG. 5, wherein themethod 500 can proceed from that point to monitor the communicationconditions, including the SINR and/or implicit NACK rate, of the uplinktransmission of the communication device and can continue from thatpoint to perform other operations of the method 500, as appropriate.

FIG. 7 presents a flow diagram of another portion of the example,non-limiting method 500 that can control the group of parametersassociated with the uplink transmission associated with thecommunication device, wherein it has been determined that that thenumber of resource blocks for the uplink transmission satisfies thedefined minimum threshold number of resource blocks and the MCS valuefor the uplink transmission satisfies the defined minimum threshold MCSvalue, in accordance with various aspects and embodiments of thedisclosed subject matter. In some embodiments, the portion of the method500 with respect to FIG. 7 can proceed from reference point B of themethod 500 as described with regard to FIG. 5. At this point, it alreadycan be determined that the number of resource blocks for the uplinktransmission satisfies the defined minimum threshold number of resourceblocks and the MCS value for the uplink transmission satisfies thedefined minimum threshold MCS value. This portion of the method 500 canbe employed to determine whether the packet repetition parameter is tobe modified to increase the amount of repetition of data packets for theuplink transmission.

At 526, a determination can be made regarding whether the amount ofrepetition of data packets for the uplink transmission satisfies adefined maximum threshold amount of repetition of data packets for theuplink transmission. The CMC can evaluate the amount of repetition ofdata packets for the uplink transmission, and can compare that amount ofrepetition of data packets to the defined maximum threshold amount ofrepetition of data packets to determine whether the amount of repetitionof data packets satisfies (e.g., meets or is the same as) the definedmaximum threshold amount of repetition of data packets.

In response to determining that the amount of repetition of data packetsfor the uplink transmission satisfies the defined maximum thresholdamount of repetition of data packets for the uplink transmission, at528, it can be determined that the packet repetition parameter is not tobe modified (e.g., to increase the amount of repetition of datapackets). In response to the CMC determining that the amount ofrepetition of data packets satisfies the defined maximum thresholdamount of repetition of data packets, the CMC can determine that thepacket repetition parameter is not to be modified, since the amount ofrepetition of data packets for the uplink transmission is already at themaximum amount of repetition of data packets permitted, in accordancewith the defined communication management criteria. At this point, themethod 500 can proceed from reference numeral 528 to reference point E,wherein the method 500 can proceed from reference point E to referencenumeral 502 with respect to FIG. 5, wherein the method 500 can proceedfrom that point to monitor the communication conditions, including theSINR and/or implicit NACK rate, of the uplink transmission of thecommunication device and can continue from that point to perform otheroperations of the method 500, as appropriate.

Referring again to reference numeral 526, if, at 526, it is determinedthat the amount of repetition of data packets for the uplinktransmission does not satisfy the defined maximum threshold amount ofrepetition of data packets for the uplink transmission, at 530, thepacket repetition parameter can be modified to increase the amount ofrepetition of data packets for the uplink transmission by a definedamount. For instance, if the CMC determines that the amount ofrepetition of data packets for the uplink transmission does not satisfy(e.g., is not at) the defined maximum threshold amount of repetition ofdata packets for the uplink transmission, the CMC can determine that thepacket repetition parameter can be modified to increase the amount ofrepetition of data packets for the uplink transmission by the definedamount (e.g., increase repetition of a data packet by one, by two, or byanother desired number), in accordance with the defined communicationmanagement criteria. Accordingly, the CMC can modify the packetrepetition parameter to increase the amount of repetition of datapackets for the uplink transmission by the defined amount.

At this point, the method 500 can proceed from reference numeral 530 toreference point F, wherein the method 500 can proceed from referencepoint F to reference numeral 502 with respect to FIG. 5, wherein themethod 500 can proceed from that point to monitor the communicationconditions, including the SINR and/or implicit NACK rate, of the uplinktransmission of the communication device and can continue from thatpoint to perform other operations of the method 500, as appropriate.

Similarly, operating system 1030can support containers, and applications 1032 can be in the form ofcontainers, which are lightweight, standalone, executable packages ofsoftware that include, e.g., code, runtime, system tools, systemlibraries and settings for an application.

Further, computer 1002 can be enable with a security module, such as atrusted processing module (TPM). For instance, with a TPM, bootcomponents hash next in time boot components, and wait for a match ofresults to secured values, before loading a next boot component. Thisprocess can take place at any layer in the code execution stack ofcomputer 1002, e.g., applied at the application execution level or atthe operating system (OS) kernel level, thereby enabling security at anylevel of code execution.

A user can enter commands and information into the computer 1002 throughone or more wired/wireless input devices, e.g., a keyboard 1038, a touchscreen 1040, and a pointing device, such as a mouse 1042. Other inputdevices (not shown) can include a microphone, an infrared (IR) remotecontrol, a radio frequency (RF) remote control, or other remote control,a joystick, a virtual reality controller and/or virtual reality headset,a game pad, a stylus pen, an image input device, e.g., camera(s), agesture sensor input device, a vision movement sensor input device, anemotion or facial detection device, a biometric input device, e.g.,fingerprint or iris scanner, or the like. These and other input devicesare often connected to the processing unit 1004 through an input deviceinterface 1044 that can be coupled to the system bus 1008, but can beconnected by other interfaces, such as a parallel port, an IEEE 1394serial port, a game port, a USB port, an IR interface, a BLUETOOTH®interface, etc.

A monitor 1046 or other type of display device can be also connected tothe system bus 1008 via an interface, such as a video adapter 1048. Inaddition to the monitor 1046, a computer typically includes otherperipheral output devices (not shown), such as speakers, printers, etc.

The computer 1002 can operate in a networked environment using logicalconnections via wired and/or wireless communications to one or moreremote computers, such as a remote computer(s) 1050. The remotecomputer(s) 1050 can be a workstation, a server computer, a router, apersonal computer, portable computer, microprocessor-based entertainmentappliance, a peer device or other common network node, and typicallyincludes many or all of the elements described relative to the computer1002, although, for purposes of brevity, only a memory/storage device1052 is illustrated. The logical connections depicted includewired/wireless connectivity to a local area network (LAN) 1054 and/orlarger networks, e.g., a wide area network (WAN) 1056. Such LAN and WANnetworking environments are commonplace in offices and companies, andfacilitate enterprise-wide computer networks, such as intranets, all ofwhich can connect to a global communications network, e.g., theInternet.

When used in a LAN networking environment, the computer 1002 can beconnected to the local network 1054 through a wired and/or wirelesscommunication network interface or adapter 1058. The adapter 1058 canfacilitate wired or wireless communication to the LAN 1054, which canalso include a wireless access point (AP) disposed thereon forcommunicating with the adapter 1058 in a wireless mode.

When used in a WAN networking environment, the computer 1002 can includea modem 1060 or can be connected to a communications server on the WAN1056 via other means for establishing communications over the WAN 1056,such as by way of the Internet. The modem 1060, which can be internal orexternal and a wired or wireless device, can be connected to the systembus 1008 via the input device interface 1044. In a networkedenvironment, program modules depicted relative to the computer 1002 orportions thereof, can be stored in the remote memory/storage device1052. It will be appreciated that the network connections shown areexample and other means of establishing a communications link betweenthe computers can be used.

When used in either a LAN or WAN networking environment, the computer1002 can access cloud storage systems or other network-based storagesystems in addition to, or in place of, external storage devices 1016 asdescribed above. Generally, a connection between the computer 1002 and acloud storage system can be established over a LAN 1054 or WAN 1056e.g., by the adapter 1058 or modem 1060, respectively. Upon connectingthe computer 1002 to an associated cloud storage system, the externalstorage interface 1026 can, with the aid of the adapter 1058 and/ormodem 1060, manage storage provided by the cloud storage system as itwould other types of external storage. For instance, the externalstorage interface 1026 can be configured to provide access to cloudstorage sources as if those sources were physically connected to thecomputer 1002.

The computer 1002 can be operable to communicate with any wirelessdevices or entities operatively disposed in wireless communication,e.g., a printer, scanner, desktop and/or portable computer, portabledata assistant, communications satellite, any piece of equipment orlocation associated with a wirelessly detectable tag (e.g., a kiosk,news stand, store shelf, etc.), and telephone. This can include WI-FIand BLUETOOTH® wireless technologies. Thus, the communication can be apredefined structure as with a conventional network or simply an ad hoccommunication between at least two devices.

WI-FI, or Wireless Fidelity, allows connection to the Internet from acouch at home, in a hotel room, or a conference room at work, withoutwires. WI-FI is a wireless technology similar to that used in a cellphone that enables such devices, e.g., computers, to send and receivedata indoors and out; anywhere within the range of a base station. WI-FInetworks use radio technologies called IEEE 802.11 (a, b, g, etc.) toprovide secure, reliable, fast wireless connectivity. A WI-FI networkcan be used to connect computers to each other, to the Internet, and towired networks (which use IEEE 802.3 or Ethernet). WI-FI networksoperate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps(802.11a) or 54 Mbps (802.11b) data rate, for example, or with productsthat contain both bands (dual band), so the networks can providereal-world performance similar to the basic 10BaseT wired Ethernetnetworks used in many offices.

An aspect of 5G, which differentiates from previous 4G systems, is theuse of NR. NR architecture can be designed to support multipledeployment cases for independent configuration of resources used forRACH procedures. Since the NR can provide additional services than thoseprovided by LTE, efficiencies can be generated by leveraging the prosand cons of LTE and NR to facilitate the interplay between LTE and NR,as discussed herein.

Reference throughout this specification to “one embodiment,” or “anembodiment,” means that a particular feature, structure, orcharacteristic described in connection with the embodiment is includedin at least one embodiment. Thus, the appearances of the phrase “in oneembodiment,” “in one aspect,” or “in an embodiment,” in various placesthroughout this specification are not necessarily all referring to thesame embodiment. Furthermore, the particular features, structures, orcharacteristics can be combined in any suitable manner in one or moreembodiments.

As used in this disclosure, in some embodiments, the terms “component,”“system,” “interface,” and the like can refer to, or comprise, acomputer-related entity or an entity related to an operational apparatuswith one or more specific functionalities, wherein the entity can beeither hardware, a combination of hardware and software, software, orsoftware in execution, and/or firmware. As an example, a component canbe, but is not limited to being, a process running on a processor, aprocessor, an object, an executable, a thread of execution,computer-executable instructions, a program, and/or a computer. By wayof illustration and not limitation, both an application running on aserver and the server can be a component.

One or more components can reside within a process and/or thread ofexecution and a component can be localized on one computer and/ordistributed between two or more computers. In addition, these componentscan execute from various computer readable media having various datastructures stored thereon. The components can communicate via localand/or remote processes such as in accordance with a signal having oneor more data packets (e.g., data from one component interacting withanother component in a local system, distributed system, and/or across anetwork such as the Internet with other systems via the signal). Asanother example, a component can be an apparatus with specificfunctionality provided by mechanical parts operated by electric orelectronic circuitry, which is operated by a software application orfirmware application executed by one or more processors, wherein theprocessor can be internal or external to the apparatus and can executeat least a part of the software or firmware application. As yet anotherexample, a component can be an apparatus that provides specificfunctionality through electronic components without mechanical parts,the electronic components can comprise a processor therein to executesoftware or firmware that confer(s) at least in part the functionalityof the electronic components. In an aspect, a component can emulate anelectronic component via a virtual machine, e.g., within a cloudcomputing system. While various components have been illustrated asseparate components, it will be appreciated that multiple components canbe implemented as a single component, or a single component can beimplemented as multiple components, without departing from exampleembodiments.

In addition, the words “example” and “exemplary” are used herein to meanserving as an instance or illustration. Any embodiment or designdescribed herein as “example” or “exemplary” is not necessarily to beconstrued as preferred or advantageous over other embodiments ordesigns. Rather, use of the word example or exemplary is intended topresent concepts in a concrete fashion. As used in this application, theterm “or” is intended to mean an inclusive “or” rather than an exclusive“or.” That is, unless specified otherwise or clear from context, “Xemploys A or B” is intended to mean any of the natural inclusivepermutations. That is, if X employs A; X employs B; or X employs both Aand B, then “X employs A or B” is satisfied under any of the foregoinginstances. In addition, the articles “a” and “an” as used in thisapplication and the appended claims should generally be construed tomean “one or more” unless specified otherwise or clear from context tobe directed to a singular form.

Moreover, terms such as “mobile device equipment,” “mobile station,”“mobile,” subscriber station,” “access terminal,” “terminal,” “handset,”“communication device,” “mobile device” (and/or terms representingsimilar terminology) can refer to a wireless device utilized by asubscriber or mobile device of a wireless communication service toreceive or convey data, control, voice, video, sound, gaming orsubstantially any data-stream or signaling-stream. The foregoing termsare utilized interchangeably herein and with reference to the relateddrawings. Likewise, the terms “access point (AP),” “Base Station (BS),”BS transceiver, BS device, cell site, cell site device, “Node B (NB),”“evolved Node B (eNode B),” “home Node B (HNB)” and the like, areutilized interchangeably in the application, and refer to a wirelessnetwork component or appliance that transmits and/or receives data,control, voice, video, sound, gaming or substantially any data-stream orsignaling-stream from one or more subscriber stations. Data andsignaling streams can be packetized or frame-based flows.

Furthermore, the terms “device,” “communication device,” “mobiledevice,” “subscriber,” “customer entity,” “consumer,” “customer,”“entity” and the like are employed interchangeably throughout, unlesscontext warrants particular distinctions among the terms. It should beappreciated that such terms can refer to human entities or automatedcomponents supported through artificial intelligence (e.g., a capacityto make inference based on complex mathematical formalisms), which canprovide simulated vision, sound recognition and so forth.

Embodiments described herein can be exploited in substantially anywireless communication technology, comprising, but not limited to,WI-FI, global system for mobile communications (GSM), universal mobiletelecommunications system (UMTS), WIMAX, enhanced general packet radioservice (enhanced GPRS), third generation partnership project (3GPP)long term evolution (LTE), third generation partnership project 2(3GPP2) ultra mobile broadband (UMB), high speed packet access (HSPA),Z-WAVE, ZIGBEE and other 802.XX wireless technologies and/or legacytelecommunication technologies.

Systems, methods and/or machine-readable storage media for facilitatinga two-stage downlink control channel for 5G systems are provided herein.Legacy wireless systems such as LTE, Long-Term Evolution Advanced(LTE-A), High Speed Packet Access (HSPA) etc. use fixed modulationformat for downlink control channels. Fixed modulation format impliesthat the downlink control channel format is always encoded with a singletype of modulation (e.g., quadrature phase shift keying (QPSK)) and hasa fixed code rate. Moreover, the forward error correction (FEC) encoderuses a single, fixed mother code rate of ⅓ with rate matching. Thisdesign does not take into the account channel statistics. For example,if the channel from the BS device to the mobile device is very good, thecontrol channel cannot use this information to adjust the modulation,code rate, thereby unnecessarily allocating power on the controlchannel. Similarly, if the channel from the BS to the mobile device ispoor, then there is a probability that the mobile device might not beable to decode the information received with only the fixed modulationand code rate. As used herein, the term “infer” or “inference” refersgenerally to the process of reasoning about, or inferring states of, thesystem, environment, user, and/or intent from a set of observations ascaptured via events and/or data. Captured data and events can includeuser data, device data, environment data, data from sensors, sensordata, application data, implicit data, explicit data, etc. Inference canbe employed to identify a specific context or action, or can generate aprobability distribution over states of interest based on aconsideration of data and events, for example.

Inference can also refer to techniques employed for composinghigher-level events from a set of events and/or data. Such inferenceresults in the construction of new events or actions from a set ofobserved events and/or stored event data, whether the events arecorrelated in close temporal proximity, and whether the events and datacome from one or several event and data sources. Various classificationschemes and/or systems (e.g., support vector machines, neural networks,expert systems, Bayesian belief networks, fuzzy logic, and data fusionengines) can be employed in connection with performing automatic and/orinferred action in connection with the disclosed subject matter.

In addition, the various embodiments can be implemented as a method,apparatus, or article of manufacture using standard programming and/orengineering techniques to produce software, firmware, hardware, or anycombination thereof to control a computer to implement the disclosedsubject matter. The term “article of manufacture” as used herein isintended to encompass a computer program accessible from anycomputer-readable device, machine-readable device, computer-readablecarrier, computer-readable media, machine-readable media,computer-readable (or machine-readable) storage/communication media. Forexample, computer-readable media can comprise, but are not limited to, amagnetic storage device, e.g., hard disk; floppy disk; magneticstrip(s); an optical disk (e.g., compact disk (CD), a digital video disc(DVD), a Blu-ray Disc™ (BD)); a smart card; a flash memory device (e.g.,card, stick, key drive); and/or a virtual device that emulates a storagedevice and/or any of the above computer-readable media.
